At the same physical size as a 250W panel, the Q CELLS 305W Mono with Black Frame is a perfect high output module for roofs where space is limited and is available now at a very cost effective price.

The new high-performance module Q.PEAK-G4.1 is the ideal solution for residential buildings thanks to its innovative cell technology Q.ANTUM. The world-record cell design was developed to achieve the best performance under real conditions – even with low radiation intensity and on clear, hot summer days.

This is a safer more reliable and cheaper way for you to receive panels and saves on the huge amounts of wasted packing materials.

​The BN tracer models have a current limiting function, you can connect twice the rated power to the controller ​so if your on a budget you can use a smaller controller with more panels so that you get more power in winter or low light but don't risk overloading the controller in the summer. The output will be limited to the max listed above.

The Tracer BN is identical to the OutBack FLEXmax Micro Series, they are made in the same factory, showing outback's faith in this MPPT manufacturer.

New Tracer series is EPsolar’s second generation of MPPT controller. Compared with CLASSIC Tracer series, it has extensive communication ability. And the die-cast aluminum design ensures excellent heat dispersion.

Compared to conventional PWM controller, MPPT technology increases the charge efficiency up to 30% and potentially decrease the power of solar array needed.

People who put performance above everything else.

Since 1926 Crown Battery has responded to the 'power' challenges and individual needs of industry leaders with the best available products and services in the field of heavy-duty commercial deep cycle batteries.

A company-wide dedication to quality control and continual improvement has earned Crown Battery the highest quality and service rating in the industry. We put more into our deep cycle batteries so you can get more out of them...

More performance, More Productivity with Less Maintenance. Nobody builds them like Crown, because no one else invests in the heaviest, thickest plates in the industry. Ours are over 10% thicker than our competitors.

Combine that with our proprietary PROeye and our low maintenance container - features that make battery maintenance predictable and efficient - and you've got a battery that's going to last longer and perform like no other.

More productivity with less maintenance

Thicker and heavier plates, combined with heavy strap and intercell connections is the 'Crown' signature

Manufactured to exact standards to deliver the longest runtime and battery life

More performance.

Crown out-performs the competition in head to head tests over and over again.

It must be a matter of perspective. But we aren’t prone to exaggeration, the way some of our competitors are.

If you claim to have batteries that out-perform all others, an independent laboratory should confirm the findings. That’s the way we do it at Crown. Since 1926, that’s all we’ve done. And to us, it really isn’t a matter of claiming to be first in the industrial marketplace. But being the best. Some manufacturers are comfortable making exaggerated claims.

We’re comfortable making battery history… one customer at a time.

The Industry Heavyweight

The heaviest, thickest plates in the industry. Thicker plates, heavier lead connections, and the most active lead material per ampere hour of rated capacity. And heavy means more lead, more active material. Which means more power. Longer life. Who would you put your money on? A lightweight battery? Or the heavyweight of the world. Crown.

Storage

Batteries should be stored in a dry and cool area in an upright position.Store batteries on a solid surface that can safely accomodate their weight. Batteries can be safely stocked two or three layers high by using a secure stacking surface placed between each layer. When stacking batteries in layers, take care to secure battery terminals against short-circuit and to block and brace batteries that prevents any movement of the battery group. Please note that batteries need periodic stock rotation and service charging to ensure peak performance.

Set of 4 Aluminium mounting brackets for mounting solar panels on vans, boats, sheds or a wooden frame as a easy cheap solar framing system.

** Panels larger than 100w are not recommended to use these alone, as a direct fixing to a vehicle roof. We suggest a bespoke solution using bolts, some of our customers use these brackets and modify them to achieve this, others get a locally fabricated solution **

MC4 Solar Connector - Price is per pair simply select the quantity as the number of pairs you want.

These are the standard connectors used on most solar panels.

TUV certified, brand new, water /weather proof rubber seal that can ensure excellent electrical contact for life time service.
The metal pin is made from high quality machined copper and sealed tip (compare to the cheap sheet metal pin) that can ensure excellent electrical contact for life time service.
Build in press tabs for easy disconnect, no tool is needed. 25A max load.
Wires should be crimped or soldered into the pins and care should be taken to get the correct pin into the correct connector. Once the pin is pushed into the connector it is difficult to remove without the correct tooling.

Features:
Shell has a strong anti-aging, anti- UV capability; found in outdoor use under harsh environment requirements; according to different needs can be arbitrary and used in conjunction with a variety of cell junction box; all connections are using press-fit connection;
